Figure 9. Structure of power dispatching data network
In above application scenarios, there are two strategies for uploading new block information: one is that the plant/substation regularly upload new block information to dispatch center, and this strategy can be realized by utilizing the automated timing devices installed in plants/substations. When the counter of timing device reaches a specified value, it triggers an interruption to upload block information. Another strategy is that local dispatch sends data summon request to plants/substations, and the corresponding plants/substations upload new block information immediately after receiving such summoning message. Under either strategy, once the event to upload new block information is triggered, P-PoW algorithm would instantly stop the real-time data filling and signature iterative calculation progress, and assembles the block header. Then, new block information is sent to local dispatch center as soon as possible.
